Assume "pkg-config zlib" works after 9.x reached EOL
Many ports passed ZLIB_CFLAGS="-I/usr/include" ZLIB_LIBS="-L/usr/lib -lz"
which is unsafe at least with lang/gcc* that override some system headers
and have newer libgcc_s.so that our old version in base may not be
forward-compatible with.

Replace USES=libtool:oldver with USES=libtool or USES=libtool:keepla in
the 32 ports that still use it. Bump PORTREVISION on their dependent
ports except the ones that depend on these:
audio/libogg
audio/libvorbis
devel/pcre
ftp/curl
graphics/jpeg
graphics/libart_lgpl
graphics/tiff
textproc/expat2
textproc/libxslt
In these cases the same trick as in the recent gettext update is used.

Bennu is a high level open source game development suite which
focuses on modularity and portability, making it a perfect choice
for cross-platform game development.
Although officialy it is only supported on Windows, Linux and GP2X
Wiz (on the right), Bennu can run on multiple other platforms,
including *BSD, MacOSX and other consoles such as the Wii, Dingoo
A320, GP2X, or the classic Xbox.
This makes it really fun to code in Bennu: the game can be played
on you computer AND your console!
